Nexium is better. Without Nexium my ulcerated esophagus would never have healed. In fact, I was taking 2 40 mg doses per day and Nexium is not ordinary omniprazole it is a derivitized/substitutes omniprazole and it does function differently.
Nexium does spend a lot of money advertizing it as an "alternative." Then they back it up by giving you a card on their site and regardless of insurance coverage, if you use the card, no matter how much the doctor prescribes you, your cost is $18.00 for the entire number of pills. In my case that is 60/month for $18.00 and that is way more than my insurance company pays. If I were to use my insurance the cost would have been $30.00/per 30 pills and they would not approve the 60 without a specialist doing a peer-to-peer.
Far better off using the company's discount card and mine is good through Decmebr 17,2013.
Unfortunately empirical evidence suggests that on-balance patients actually do better on the older generation of proton pump inhibiters.
I am not suggesting you are fibbing, but Nexium spends lots of advertising dollars to convince patients that their Brand name is somehow superior to ordinary omniprazole.
Nexium is a varient of an older out-of-patent drug that does the same thing. The problem is not resolvable, unfortunately.
